A string of robberies that started last Thursday is prompting Madison police to deploy more resources on the city's north side.
Authorities said that in all four robbery cases, the perpetrators have been riding bicycles. Now, police said that they're stepping up their presence.
"We are doing everything possible to identify the suspects in these cases and bring a stop to this disturbing trend," said Madison Police Capt. Cam McLay.
Jogger Joe Jahnze said he was surprised to hear what had been happening in his neighborhood.
"Yeah, a little. I mean, with the golf course there and then the military guys do a lot of running around here, too," said Jahnze, a north side resident.
Detectives said that they believe there is a strong likelihood that some of these robberies, if not all of them, are linked together. Two cases involved multiple robbers in which no weapons were seen. Another case involved a single gunman and a shot was fired, police said.
